Red Hat Security Advisory: libtiff security update

Important

Stack-based buffer overflow in the tiffsplit command in libtiff 3.8.2 and earlier might might allow attackers to execute arbitrary code via a long filename. NOTE: tiffsplit is not setuid. If there is not a common scenario under which tiffsplit is called with attacker-controlled command line arguments, then perhaps this issue should not be included in CVE.

Multiple stack-based buffer overflows in the TIFF library (libtiff) before 3.8.2, as used in Adobe Reader 9.3.0 and other products, allow context-dependent attackers to execute arbitrary code or cause a denial of service via unspecified vectors, including a large tdir_count value in the TIFFFetchShortPair function in tif_dirread.c.

Heap-based buffer overflow in the JPEG decoder in the TIFF library (libtiff) before 3.8.2 allows context-dependent attackers to cause a denial of service and possibly execute arbitrary code via an encoded JPEG stream that is longer than the scan line size (TiffScanLineSize).

Heap-based buffer overflow in the PixarLog decoder in the TIFF library (libtiff) before 3.8.2 might allow context-dependent attackers to execute arbitrary code via unknown vectors.

Heap-based buffer overflow in the NeXT RLE decoder in the TIFF library (libtiff) before 3.8.2 might allow context-dependent attackers to execute arbitrary code via unknown vectors involving decoding large RLE images.
